Flanged Type Check Valves Made in Tianjin China
Flanged type check valves designed to be bolted between pipe flanges, preventing backflow in pipelines where automatic closure is required without manual intervention.

View SpecificationBuyers This Category Suits
- Water utility engineers specifying backflow protection in municipal supply and drainage networks
- Power plant maintenance teams needing reliable check valves for feedwater and condensate lines
- Chemical and petrochemical plant operators requiring corrosion-resistant check valves for process piping
- Marine engineers installing check valves in shipboard ballast and cooling systems
- Pharmaceutical and metallurgical plant procurement managers sourcing valves for clean and high-purity service
What It Fixes on the Line
- Backflow in pipelines causes contamination in water supply and process systems, especially in pump discharge lines
- Existing check valves fail to close quietly, causing water hammer and mechanical stress on pipe supports
- Valves with inconsistent body materials or sealing surfaces lead to premature leakage in corrosive or high-pressure environments
- Lack of standardisation across valve types makes spare parts inventory difficult to manage across multiple plant systems
- Limited availability of check valves in large diameters (DN2600) from single suppliers delays project timelines
Why Engineers Specify This Family
Advantage
Flanged connection allows secure bolted installation between standard pipe flanges, suitable for high-pressure and high-temperature service
Advantage
Multiple types available including swing, lift, and ball type designs to match flow direction, pressure, and closure speed requirements
Advantage
Body materials include cast iron and other options suitable for water, steam, oil, and chemical media across the nominal diameter range
Advantage
Valves are manufactured under ISO 9001 and ISO 14001 systems, ensuring consistent quality and environmental compliance
Advantage
Nominal diameter range from DN10 to DN2600 covers small service lines to large industrial pipelines in one supplier solution
Where These Valves Are Installed
- Preventing reverse flow in pump discharge lines in municipal water treatment plants
- Protecting feedwater systems in power generation units from backflow during pump shutdown
- Ensuring safe operation in chemical process piping where media reversal could cause reaction hazards
- Installing check valves in shipboard cooling and ballast systems to prevent water surge during engine stoppage
- Maintaining system integrity in pharmaceutical clean-in-place (CIP) loops where backflow must be strictly avoided

Flanged Type Check Valves FAQ
What types of flanged check valves are available?
We offer swing type, lift type, and ball type check valves in flanged end configurations, with models designed for different pressure and flow conditions.
Can I get a check valve with a specific body material?
Yes. Body materials include cast iron and other options suitable for water, steam, oil, and chemical media. Material selection is confirmed on request.
What sizes and pressures are available?
Our flanged check valves cover nominal diameters from DN10 to DN2600 mm and nominal pressures from 0.05 to 4.0 MPa. Exact size and pressure per model are confirmed on quotation.
Are the valves tested before shipment?
Yes. Each valve undergoes inspection and testing at our plant before packing. Test records are available on request.
Do you supply mixed orders with other valve types?
Yes. Flanged check valves can be shipped together with butterfly valves, gate valves, strainers, and actuators in a single container.
What certifications does the factory hold?
Tianjin MIC Valve Co., Ltd. holds ISO 9001 quality management and ISO 14001 environmental management certification. Test records for your order are issued on request.
